Application lcd June 27, 190B. Serial No. 267,178.

To all 'whom it may concern.' I

lie it known that l, HENRY W. i enorm', citizen of the United States, and nesident of v Syracuse, in the county of Onondaga and l key and the associatedparts which contro the escagement mechanism.

The o ject of my invention is to produce a simple and eilicient mechanism of the char actor specified and one in which a minute adjustment ma be efl'ected between the spacin key an the escapement mechanism.

To t 1e above and other ends, which will hereinafter' appear, my invention consists 1n `the features of construction, arrangements of arts and combinations of devices to be hereinafter described and claimed.

iIn the accompanying drawings wherein like reference characters indicate corre spending parts in the different views, Figure 1Y is a vertical front .to rear sectional view of one form of typeWi-iting machine showin my invention applied thereto, and Fig. 2 is a' detailed top plan view of a portion of the machine with arts broken away to better illustrate other eatures of tliedevice.-

l have shown m invention applied, to a' Monarch tyewritmg machine, though it should he un erstood tliat-thkeinventon may be applied to various other f orn'is of, type- I writing machines.

In the drawings, 1 indicates the base of the machine from which corner posts 2 prov ject, thecorner posts supporting a top plate 3. A suitable carria e (not shown) travels from side to side of le machine and carries a platen 4 diagrammatically shown in Fi 1. K'ey levers 5 are fiilcruined against a ful cruniy late (i, which is secured to the base of one o the machines; the forward ends of the key levers are provided with the usual finger keys 7, and each key lever has an npi'ight sub-lever 8 pivoled thereto at 9 and the lower end of each sub-lever is bifurcated at 10 for the reception of a fulcrum rod 11, which extends transversely' beneath the key. levers and is secured at its ends to the base of the machine. The upper end of each sub-lever 8 is pivoted at 12 to a forwardly extending link lil which in tun-n i pivoted at its forward end ll to n type ha: l5. The various type hars are pivoted on :i pivot wire lo sup )orted on u typo bar seg' nient l?. und worV in slots 18 in n serian-,nl und ure segnieiitally arranged :nifl :niiipled to swing upwardly and rearwardly lo lh( printing point. Type bur restoring springs lil areeach connected at one end lo a hook 20 and at the other end to a link 21, which in turn is pivotcd to the associated tvpc hai'.

lilxtending transversely beneath the vari ous key levers 5 is a universal har Q2 that is connected it its ends to levci-lilie arms 2:5.

which, with the universal har, torni a yoke.l The lever-like arnw` are rigidly secured to a rock shaft 24 which extends between depend' ing bracket ilutes 2i', thil latter being se cured to thc asc of the machine und carry ing hearing screws 24 on which thc. shaft .24 turns. The forward ends of the lcvcrdikc arms extend over and are adapted to co operate with adjustable set scri-ws or devices .25 and are operatively connected to the spacing bai' of the machine. as will hereinafter more clearly appear. liojcciinff rearwardly from thc rock' sli-.ift 24 is u rigidly connected aini`2fl to which an npi'ifht link 2 is pivoted at'l. The 'upper ein ofthe link is pivotcd at 29 to a forwa. illy projecting arm-30 of a dog rocker which has a rocltshnt from which an upwardly projecting arm 32 e tends, the arm 32 carrying the` usual feeddog 33 which cooperates s nh u feed rack 24 diagrammatically shown in Fig. l:l it bring understood that the'ruck 34 is operatively connected with the carriage. .Xn :ii-in cxtends foi-wurd] from thc rock shalt :il und has un upwardly wives one cud of a coiled restoring spring 21T. thc upper ond of said spring being rcccivcd on n similar tout projecting from :i brui-hrt 1H secured lo n cross har 35? on the buse o. thc nnnhnc. Thuv it will he seen that the parts 2Q, 23, 24, 2G and 35 constitute a frame that is o erativel connected to the cscapenientand tiat the orwardly project ing ends of the lever-like arms 23 of said frame coact with the screws 25. The springr 37 tends to restore the universal bar and the parts connected thereto to their normal positions, as represented in Fig. 1. A spacing bar 39 is connected at its ends to the forward ends of sheet meta:` spacing levers 40 L hase l.

which are united near the rear end portions by a transversely extending bracing `strip 41. The levers 40 are' pivoted on a ivot rod 4;! which extends from side to si e of he machine and is secured at its ends to the The levers 40 extend beyond the pivoted rod 42 and have suitable beaiin s or the set screws 25, hereinbefore describe and inthe present instance `the levers are shown as bent inwardly at 43 and are perforated und tapped to receive the set screws which extend therethrough, and the u per ends of the screws are adapted to ar against the forward ends of the lever-like urnis 23 which are connected to the universal bar, thus transmitting motion to the universal bar, the rock shaft 24, the rearwardly extending arm 26, link 27 and the dog rocker. From the foregoing description it will be understoodihat the screws 25 constitute individual adjusting means by which any inaccuracies in the spacing bar frame or the universal bar frame may be compensated foi', and by which a uniform extent of dip may be given to thespace key irrespective of any variations in the throw of the dog rocker. Furthermore, it. will be observed that the adjustment of the screws to control the di of the space key ma be effected without ii fecting the universe bar or the escapeinent. The adjusting screws likewise afford individual adjusting means between each spacing key levier and each lever-like arm 23 of the universal bar for causing proper engage- 'ment between the two.

l.Thee spacing har. lewis 40 and the strengthening or connecting strip 41 form a four-sided substantiallyrectangular frame which is restored to its normal position by springs 44, each of' which is bent inwardly at its forward end` as indicated at 45. and bears upon the upper side of a spacing lever 40 near the inwardly beiit,portion 43 so as without atlecting the normal Yposition of the latter.

'hat l claim ns nevi und desire to secure by Letters lateiit, isr- 1. ln 'a' typewriting machine, the combi nation of sheet. metal levers connected at` their forward ends by a space key and each having a threaded bearing:r :it thil rear end ythereof and iii the rear oi' the pivot of said level'. screws carried by and adjustable in said bearings. a universal bar. nud a frame to which said har is connected. said i'raniev 'which connects said levers iiiid forms a foursided frame with said levers and spacing key, ,screws carried by and adjustable iii the bearings in said levers` ii universal bar, and a pivoted frame to which said bnr is connected, said pi'voted frame having forwardly projecting arms with which said screws are adapted to contact.

3. 1n a typewriting machine. the combination of a universal bai-,lever-like arms to which said universal bar is connected, a rockshaft to which said lever-like arms are rigidly connectedand by which the lever-like arms and universal bar are supported, escapement mechanism, connections from said rock shaft to saidescapement mechanism, pivoted spaceffkey levers. a Space key that connects the forward ends of said levers, a strengthening bar that. unites the space key levers forward of the pivots thereof, and an adjustable screw between the rear end of each of said space key-levers and the forward end of each of the lever-like arms of the universal bar.
